O.J. Simpson’s former manager, Norman Pardo, is making a documentary about the infamous murders — presenting the case that Simpson “didn’t act alone.”

Pardo — who describes himself as a friend of the NFL-great-turned-con, and worked with O.J. for nearly 20 years after his acquittal — has been developing the film for four years with co-executive producer Dylan Howard.

The series will be pitched next week to streaming services, cable and premium networks to coincide with the 25th anniversary of the homicides of Nicole Brown and Ron Goldman.

“For the first time, the most thorough investigation into the murder ever conducted will be shared with America,” said Pardo, who claims to have more than 70 hours of video of Simpson that nobody has seen. “We have assembled a team of internationally renowned criminal investigators, experts and lawyers,” he said.

“And they believe they can not only prove Simpson was involved in their deaths — but for the first time reveal he had at least one accomplice.”

Howard is behind the Discovery ID crime series “An American Murder Mystery” and the Reelz series “National Enquirer Investigates.”
